WAGON-AX LE.

SPECIFICATION forming part of Letters Yatent No. 465,625, dated December22, 1891.

Application tiled March 23, 1891. Serial No. 386,097. (No model.)

To @ZZ whom t may concern.-

Beit known that LWILLIAM NEHR1NG,a citizen of the United States,residing at Evansville, in the county ot' Vanderburg and State ofIndiana, have invented certain new and useful Improvements inVVagon-Axles, ot' which the following specification, taken in connectionwith the accompanying drawings, is a full, clear, and exact description,such as will enable those skilled in the art to which they appertain tomake and use the same.

My invention relates to improvements in that class of wagon-axles inwhich detachable hollow axle-spindles are employed; and the object of myVinvention is to provide an axle which will be simple in constructionand at the same time strong, durable, and effective.

My invention consists, principally, of three features of novelty: first,an improved axle composed of a wooden core and strengthening-strips ofmetal; second, a detachable hollow spindleprovided with a detachablewearstrip of peculiar construction, and, third, an improved arrangementfor utilizing the hollow spindle foraiubricating-chamber and myinvention consists of other features of novelty, all of which will befirst described with reference to the accompanying drawings, and thenmore particularly pointed out in the claims.`

Fig. VII is a sectional view taken on line VII VII of Fig. II. Fig. VIIIis a side elevationof my improved clip. Fig. IX is a sectional view ofmy improved spindle having a slightlymodified form of wear-strip. Fig. Xis a similar sectional view showing the same form of wear-strip withoutthe perforation for the passage of oil.

Like letters of reference indicate the same parts throughout the severalviews.

Arepresents the axle, B the hollow spindles, and C the securing-clips.The axle A is constructed to receive my improved form of spindle, aswill presently appear.

The spindle B is formed with the bearing portion b forithe reception ofthe wheel and the socket portion Z9 for fitting over the end of theaxle. The socket h has a shoulder b2, against vwhich a similar shoulderon the axle abuts. b3 is a convex groove formed on the under side of thespindle B and adapted to receive a convex wear-strip D. The strip D isconfined from longitudinal movement between the socket portion o and ashoulder b4 at the outer end of the groove hsl E is a collar` adapted toiit on the spindle and hold the inner end of the wear-strip snuglyagainst the spindle. e is a lug formed on the upper surface of thespindle B and adapted to engage in a notch e', formed in the inner edgeof the collar E, to prevent its turning. The spindle has the custo maryscrew-threaded nib h5 at its outer end for the reception of thewheel-retaining nut F, which nut is formed with an annular collar f,which engages the outer end of the wear-strip D for holding it againstthe spindle.

G are washers iittin g on the spindle against the collars E and f andprovided with lugs g, which engage in notches in said collars, wherebythey are prevented from turning, so that they can take up all the wearon their bearing-faces.

The hollow or cavity D of the spindle B is utilized for anoil-reservoir, the oil being conned in the outer half of the cavity byshoulders or dams bi.

l1 is an oblong perforation or slit in the bottom Wall of the reservoirb, which registers with a similar slit d in the center of the WearstripD. The outer or bearing surface of this wear-strip D is provided withoil-distributing grooves d', leading from the ends ot' the slit @wherebyoil passing from the reservoir h6 is fed Vto the wheel-bearing. Thenibl/5 is perforated longitudinally, and the nut F is also perforatedand provided Witha suitable cover or door fwhereby the nowilmay bereadily inserted intothe-reservdir; or, if preferred, the nut F may beformed whole without the persuitable perforations.

foration,wlien it will be necessary to remove it from the axle when itis desired to insert the oil into the hollow spindle.

The axle A is formed of a central strip or core a of wood and two outerinclosing strips or thin bars a of tempered' iron or steel, the partsbeing securely riveted or bolted together by means of rivets or boltsa2, passing through The ends of the axle are formed with shoulders a3,which, when the spindles B are put in place, abut against the shouldersb2 and the edge of the upper surface of the spindle-sockets, wherebywhen the clip C and the bolts or rivets are put in place a secure jointis formed between the axle and detachable spindles and a stout andeconomical axle formed. It is obvious that the axle and spindles areperforated at the proper places for the reception of the bolts and thecentral bolt of the clip C.

. The clip C is provided with the customary screw-threaded bolts or armsc, the keeper c', perforated to tit over these bolts, and nuts c2 toretain the keeper in place. In addition to this, in my improved clip Iprovide a central perforation in the keeper and one in the arch of theclip, through which a central bolt c3 passes and holds the clip securelyin position. This form of clip is of particular advantage in combinationwith my improved wagon-axle, as it makes it impossible for the clip toslip longitudinally out of place.

In Figs. IX andX I have shown a modified form of wear-strip applied tomy improved axle-spindle. In this form the small or outer end of theconcave wear-strip D is 'provided with a retaining-hook cl2, adapted toengage in a perforation cl3 in the under side of the spindle B, whichassists in holding the wearstrip to the spindle. The collar E andretaining-nut F are also employed in combination with this form, theprincipal function of the hook cl2V being to retain that end of thewearstrip in position when the nut and'wheel are removed. L L areperforated ears or lugs formed on the enlarged end of the detachablespindle, through which thearms of the clip C may pass.

Figs. IX and X differ only in the omission of the centrallubricating-chamber from Fig. X, in place of which the lubricant may besupplied as is now commonly done.

The hollow spindle may be formed of a metal casting o r of a solidforged piece of metal, with the oil-chamber bored in. The wear-strip isformed of any suitable metal which is softer than the journal-box of thewheel, so that the wear is taken up entirely by said strip and thespindle and wheel are protected.

Having thus fully described my invention, the following is what I claimas new therein and desire to secure by Letters Patent:

l. An axle-spindle having aconcave groove in its surface, in combinationwith a concave wear-strip adapted to fit in said groove, and

suitable collars fitting on the spindle and enon the spindle, wherebythe collar is prevented froln turning, substantiallyas set forth.

Ll. The combination of an axle-spindle with a wear-strip set in itssurface, said wear-strip being formed of softer m etal. than thespindle, whereby it takes up the wear and'protects the spindle andjournal-box of the wheel, as herein set forth.

5. `The combination of a hollow axle-spindle, a wear-strip, means forconnecting the wear-strip to the spindle, and a perforation through thespindle and strip, substantially as set forth.

6. The combination of a hollow axle-spindle, an oil-inlet, shoulders ordams formed in said hollow spindle for conning the oil, and anoil-outlet, as herein set forth.

7. The combination of a hollow axle-spindle, dams formed in said spindlefor confining the oil, an oil-outlet, an internally-screw threadedretaining-nut adapted to engage the end of said spindle, and anoil-inlet door in said nut, whereby the oil can be placed in saidspindle behind the outer dam, as herein set forth.

8. An axle-spindle formed with agroove on its surface, a wear-stripiittin g in said groove, a hook formed on one end of the wear-strip andadapted to engage in a perforation in the spindle, and a collar adaptedto engage the other end of the wear-strip, substantially as set forth.

9. The combination of an axle-spindle, a socket-piece formed thereon,perforated lugs or ears L, the axle A, and a clip, substantially as setforth.
